What is the result when this program is executed?
A. Bob’s Name: Bob
B. Bob’s Name: Jian
C. Nothing prints
D. Bob’s nameCorrect Answer: BExplanation
Explanation/Reference:Explanation:
After the statement jian = bob; the jian will reference the same object as bob.QUESTION 3Given the 1Z0-803 dumps code fragment:

What is the result?
A. Valid
B. Not valid
C. Compilation fails
D. An IllegalArgumentException is thrown at run timeCorrect Answer: CExplanation
Explanation/Reference:Explanation:
In segment ‘if (valid)’ valid must be of type boolean, but it is a string.
This makes the compilation fail.QUESTION 4Given:

What is the result?
A. 6
5
6
4
B. 6
5
5
4
C. 6
5
66
D. 6
5
6
5Correct Answer: AExplanation
Explanation/Reference:Explanation:
Within main z is assigned 6. z is printed. Output: 6 Within doStuff z is assigned 5.DoStuff2 locally sets z to 4 (but MyScope.z is set to 4), but in Dostuff z is still 5. z
is printed. Output: 5
Again z is printed within main (with local z set to 6). Output: 6 Finally MyScope.z is printed. MyScope.z has been set to 4 within doStuff2(). Output: 4QUESTION 5Which two are valid instantiations and initializations of a multi dimensional array?

A. Option A
B. Option B
C. Option C
D. Option D
E. Option E
1Z0-803 pdf Correct Answer: BDExplanation
Explanation/Reference:Explanation:
In the Java programming language, a multidimensional array is simply an array whose components are themselves arrays.QUESTION 6An unchecked exception occurs in a method dosomething() Should other code be added in the dosomething() method for it to compile and execute?
A. The Exception must be caught
B. The Exception must be declared to be thrown.
C. The Exception must be caught or declared to be thrown.
D. No other code needs to be added.Correct Answer: DExplanation
Explanation/Reference:Explanation:
Because the Java programming language does not require methods to catch or to specify unchecked exceptions (RuntimeException, Error, and their subclasses),
programmers may be tempted to write code that throws only unchecked exceptions or to make all their exception subclasses inherit from RuntimeException. Both
of these shortcuts allow programmers to write code without bothering with compiler errors and without bothering to specify or to catch any exceptions. Although
this may seem convenient to the programmer, it sidesteps the intent of the catch or specify requirement and can cause problems for others using your classes.QUESTION 7Given the code fragment:

A. Option A
B. Option B
C. Option C
D. Option D
E. Option ECorrect Answer: ACEExplanation
Explanation/Reference:Explanation:
A: Throwing the same exception is fine.
C: Using a subclass of java.io.IOException (here java.io.FileNotFoundException) is fine
E: Not using a throw clause is fine.
Incorrect answers:
B: Exception is not a subclass of java.io.IOException and cannot be used here.
D: Not extends. SampleCloseable cannot be the superclass of Test, a superclass must be a class.
(An interface extends other interfaces.)QUESTION 9Given the code fragment:
Int [] [] array = {{0}, {0, 1}, {0, 2, 4}, {0, 3, 6, 9}, {0, 4, 8, 12, 16}}; Systemout.printIn(array [4] [1]);
System.out.printIn (array) [1] [4]);
What is the result?
A. 4
Null
B. Null
C. An IllegalArgumentException is thrown at run time
D. 4
An ArrayIndexOutOfBoundException is thrown at run time
1Z0-803 exam Correct Answer: DExplanation
Explanation/Reference:Explanation:
The first println statement, System.out.println(array [4][1]);, works fine. It selects the element/array with index 4, {0, 4, 8, 12, 16}, and from this array it selects the
element with index 1, 4. Output: 4
The second println statement, System.out.println(array) [1][4]);, fails. It selects the array/element with index 1, {0, 1}, and from this array it try to select the element
with index 4. This causes an exception.
Output:
Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: 4QUESTION 10Given:

How many times is 2 printed as a part of the output?
A. Zero
B. Once
C. Twice
D. Thrice
E. Compilation fails.Correct Answer: DExplanation
Explanation/Reference:
QUESTION 11Given:

Which two actions, used independently, will permit this class to compile?
A. Adding throws IOException to the main() method signature
B. Adding throws IOException to the doSoomething() method signature
C. Adding throws IOException to the main() method signature and to the dosomething() method
D. Adding throws IOException to the dosomething() method signature and changing the catch argument to IOException
E. Adding throws IOException to the main() method signature and changing the catch argument to IOException1Z0-803 dumpsCorrect Answer: CDExplanation
Explanation/Reference:Explanation:
The IOException must be caught or be declared to be thrown. We must add a throws exception to the doSomething () method signature (static void doSomething()
throws IOException).
Then we can either add the same throws IOException to the main method (public static void main (String[] args) throws IOException), or change the catch
statement in main to IOException.QUESTION 12Given:

What is the result?
A. Hello
B. Default
C. Compilation fails
D. The program prints nothing
E. An exception is thrown at run timeCorrect Answer: AExplanation
Explanation/Reference:Explanation:
The program compiles fine.
The program runs fine.
The output is: helloQUESTION 13Given:
